avionics

avionics (āˌvēŏnˈĭks), electronic instruments used in air or space flight; also the design and production of such instruments. Early planes had few instruments, but as aviation and aircraft became more complex, so did instrumentation. Most of the new technology was electronic; hence, the expression “aviation electronics” arose and was later shortened to “avionics.” After World War II, the increasing sophistication of military avionics helped spawn a proliferation of electronic applications to commercial and private aviation. Avionics includes numerous types of devices, including those used for navigation (see air navigation); control instruments that aid in steering and controlling the craft; and performance indicators, such as altimeters and velocity gauges.

avionics

A field of applied research in which electronic devices are adapted to use in aviation. Avionics are aeronautical electronics, not necessarily restricted to aerodynes only. Although the term implies use of equipment in airborne applications only, it also extends to ground-based equipment like radar and surface-to-air weapons.
